Slot Format Configuration Method and Communications Apparatus

2. The method according to claim 1, wherein the second configuration information is dynamic signaling.

4. The method according to claim 1, wherein the type of each symbol in each of the slots is selected from a plurality of possible types of symbols, the plurality of possible types of symbols further comprise a flexible symbol and/or a silent symbol, the flexible symbol is configured by using the first configuration information, the flexible symbol refers to a symbol whose transmission direction is not determined, the silent symbol indicates that the first node does not communicate with the third node, the subset of slots are one or more slots each has at least one flexible symbol, and the slot formats of the subset of slots are modified by modifying one or more flexible symbols in the subset of slots to one or more uplink symbols, one or more downlink symbols, and/or one or more silent symbols.

8. The method according to claim 5, wherein the type of each symbol in each of the slots is selected from a plurality of possible types of symbols, the plurality of possible types of symbols further comprises a flexible symbol and/or a silent symbol, the flexible symbol is configured using the first configuration information, the flexible symbol refers to a symbol whose transmission direction is not determined, and the silent symbol indicates that the first node does not communicate with the third node.

10. The communications apparatus according to claim 9, wherein the second configuration information is dynamic signaling.

12. The communications apparatus according to claim 9, wherein the type of each symbol in each of the slots is selected from a plurality of possible types of symbols, the plurality of possible types of symbols further comprise a flexible symbol and/or a silent symbol, the flexible symbol is configured using the first configuration information, the flexible symbol refers to a symbol whose transmission direction is not determined, the silent symbol indicates that the communications apparatus does not communicate with the third node, the subset of slots are one or more slots each has at least one flexible symbol, and the slot formats of the subset of slots are modified by modifying one or more flexible symbols in the subset of slots to one or more uplink symbols, one or more downlink symbols, and/or one or more silent symbols.

15. The communications apparatus according to claim 14, wherein the receiver is further configured to receive first indication information from the first node, wherein the first indication information indicates modified slot formats of a subset of slots in the first set of slots.

16. The communications apparatus according to claim 13, wherein the type of each symbol in each of the slots is selected from a plurality of possible types of symbols, the plurality of possible types of symbols further comprises a flexible symbol, the subset of slots are slots in which flexible symbols are located, the flexible symbols are configured using the first configuration information, and the flexible symbols refer to symbols whose transmission directions are not determined.
